net: phy: mscc: macsec initialization This patch adds support for initializing the MACsec engine found within some Microsemi PHYs. The engine is initialized in a passthrough mode and does not modify any incoming or outgoing packet. But thanks to this it now can be configured to perform MACsec transformations on packets, which will be supported by a future patch. The MACsec read and write functions are wrapped into two versions: one called during the init phase, and the other one later on. This is because the init functions in the Microsemi PHY driver are called while the MDIO bus lock is taken. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S.

net: phy: mscc: fix copyright and author information in MACsec All headers in the MSCC PHY driver have been copied and pasted from the original mscc.c file. However the information is not necessarily correct, as in the MACsec support. Fix this.

net: phy: mscc: split the driver into separate files This patch splits the MSCC driver into separate files, per functionality, to improve readability and maintenance as the codebase grew a lot. The MACsec code is moved to a dedicated mscc_macsec.c file, the mscc.c file is renamed to mscc_main.c to keep the driver binary to be named mscc and common definition are put into a new mscc.h header. Most of the code was just moved around, except for a few exceptions: - Header inclusions were reworked to only keep what's needed. - Three helpers were created in the MACsec code, to avoid #ifdef's in the main C file: vsc8584_macsec_init, vsc8584_handle_macsec_interrupt and vsc8584_config_macsec_intr. The patch should not introduce any functional modification. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>

net: phy: mscc: fix initialization of the MACsec protocol mode At the very end of the MACsec block initialization in the MSCC PHY driver, the MACsec "protocol mode" is set. This setting should be set based on the PHY id within the package, as the bank used to access the register used depends on this. This was not done correctly, and only the first bank was used leading to the two upper PHYs being unstable when using the VSC8584. This patch fixes it.
